It's not just Grimes, it's just giving up picks that would prevent us from drafting someone to replace him.
Picks and on top of that pick swaps, and young players. One of those picks could end up being better than Donovan Mitchell (13 pick).
Let the season playout. They need to move him more than we need to trade for him. They really don't want to start the season with him on the roster. They are trying to tank to get that guy from France.
If we giving up that much we should do a pick swap for next season.
